ABOUT RETELL AI

Retell AI is using first-principles thinking to reimagine the call center with cutting-edge voice AI. Thousands of companies now use Retell's AI voice agents to handle sales, support, and logistics calls that once required large teams of human agents. Backed by Y Combinator, Alt Capital, and other leading investors, we've scaled to $80M in ARR with a team of 50, up from $5M at the start of 2025, and are now valued at over $1.5B.

Our vision for 2026 is to build a modern CX platform where entire contact centers are powered by AI. Instead of basic automation that needs constant human tuning, we're creating intelligent AI “workers” that act as frontline agents, QA analysts, and managers, continuously executing, monitoring, and improving every customer interaction.

We're growing fast and looking for ambitious builders who want to tackle hard technical problems, move quickly, and have a real impact on one of the fastest-growing voice AI companies in the world.

Let's build the future together.

ABOUT THE ROLE

Retell AI transforms customer experience with voice AI for enterprises, including customers like CVS/Aetna, American Airlines, Lenovo, and Grab. We have more customer stories than we can tell!

As a Frontend Engineer at Retell AI, you’ll build the user experiences that power our voice automation platform from prompt management and dashboards to analytics and customer-facing tools. You’ll design and ship intuitive, responsive interfaces using React and TypeScript, working closely with backend and DevOps partners to ensure everything is fast, reliable, and scalable.

You’ll own frontend projects end to end, collaborate directly with customers to onboard and debug real-world use cases, and turn feedback into meaningful UX improvements. This is a hands-on, high-impact role where you’ll move quickly, take ownership, and help shape a product used in production by teams building with voice AI.

Develop responsive, intuitive interfaces using React, TypeScript, HTML, CSS, and JavaScript.
Collaborate on backend APIs and DevOps to ensure seamless, scalable systems.

Work with customers to onboard, debug, and turn feedback into UX improvements.

YOU MIGHT THRIVE IF

Have 2+ years of experience building production-grade apps with React and TypeScript.
Hold a degree in CS, CE, or equivalent practical experience.
Take ownership like a founder, proactively solving problems with clean design thinking.
Thrive in fast-paced environments, quickly learning new tools and frameworks.
Collaborate effectively, balancing clarity and momentum in small, dynamic teams.
